This week we had 17 new APIs added to our API directory. 4 notable new entries include a third party photo sharing service for Twitter, a cloud storage API, an API for managing embeddable talking avatars, and an API for publishing photo books. Below is more detail on each of these APIs.

img.ly API: img.ly is a third party social photo sharing service for Twitter. Users can browse, upload and tag photos. The service generates a URL for the photos and the API allows users to connect their application to img.ly. It uses a RESTful architecture and responses are formatted in XML or JSON.

Mezeo Cloud Storage Platform API: Mezeo Cloud Storage Platform is an on-demand service that exposes cloud storage with a RESTful API. The API allows developers to store, organize, share and publish content as well as rich meta-data. The API responses are formatted in XML or JSON.

Blurb API: Blurb is a company and a community "that believes passionately in the joy of books and reading them, making them, sharing them, and selling them. With the launch of our API, we want to help you help your community of book lovers become bookmakers." The Blurb API gives developers the ability to programmatically publish photobooks onto the Blurb publishing platform. There are two types of APIs supported: the first is a Photobook resource that lets you generate an XML list of your photos and POST it to the Photobook Resource. The second is a book pricing resource which allows your application to show prices in various currencies for various book combinations. The API uses a RESTful interface and responses are formatted in XML.
